BIRMINGHAM, Alabama -- Interstate 20's westbound lanes -- which have been closed for construction for about two months -- are scheduled to reopen Thursday evening, according to the Alabama Department of Transportation.

When reopened, the contractor team of Dunn Construction Co. and APAC Mid-South Inc., will have refurbished the entire interstate between Interstate 20/59 at Birmingham-Shuttlesworth International Airport and Interstate 459 in Leeds.

Other work may still be done along the highway as the $38.6 million project continues, ALDOT spokeswoman Linda Crockett said.

Traffic has been rerouted along I-459 and Interstate 59 during the closure, which has led to heavier than usual inbound delays along I-59 through Trussville and Roebuck, and other roadways including U.S. 78 and several streets in Irondale.

Under their contract, workers have until Thanksgiving to complete the project.

There is an incentive of $30,000 per day for each day the entire project is completed ahead of schedule and a daily penalty of the same amount if late.
